The Lowdown
Alright folks, Rusty here. Let’s get straight into it for this stretch of coast.
Well, I’ve gotta be honest with you, the outlook for the next couple of weeks is a bit of a bummer. We’re looking at a long, dry spell with hardly anything worth paddling out for. The first real glimmer of something surfable doesn’t show up until Tuesday, September 15th, and even then, it’s a bit of a mixed bag.
For the first week, from Monday, September 7th right through to Monday, September 14th, it’s flat or close to it. We’re talking tiny, weak waves that barely register. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, but that’s about the only bright spot. You’ll see a lot of glassy mornings and clean afternoons, but with nothing to ride, it’s just a pretty lake.
The only time the ocean shows a pulse is on Tuesday, September 15th. Kennebunk Beach is the only spot in the game, and it’s our best—and really only—option. The combined swell energy jumps to a moderate 164, with a 5 ft swell coming from the SSE. The wind is a clean cross-offshore from the E at 12 mph, so the morning session should look pretty tidy. The period is a short 6 seconds though, so it’ll be a bit fat and lumpy, not the cleanest shape. This is a beach break, so with that short period and moderate energy, it might actually be more fun for a kite surfer than a paddle surfer. Still, if you’re desperate for a wave, this is your window.
After that, it’s back to the grind. The rest of the week into the weekend of the 20th and 21st is mostly tiny, weak, and onshore. There are a few glassy moments on the 17th and 18th, but the swell is barely 1 ft. It’s a consistent pattern of gentle cross-onshore breezes and small, choppy waves. Nothing to get excited about.
So, to wrap it up: hold your horses. The only standout is that Tuesday the 15th, with a 5 ft SSE swell and clean offshore winds. It’s not a classic, but it’s the only game in town. For the rest of the 16 days, it’s a long wait. Don’t sell your board, but maybe work on your tan.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
